Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a meibomian gland hot impulse interventional treatment device. Background Art

[0002] With the widespread use of electronic products, dry eye has become one of the important and common eye diseases, seriously affecting people's quality of life. According to statistics, the global incidence of dry eye is 5.5%-33.7%, and in my country it is 21-33%. Therefore, paying attention to the diagnosis and treatment of dry eye has become an important research topic in ophthalmology. Among them, 70% of dry eye is caused by meibomian gland dysfunction (MGD), and the proportion of MGD in dry eyes is as high as 87.6%. Therefore, the research and development of medical equipment for MGD is one of the important development directions for the treatment of dry eye.

[0003] The meibomian glands are located within the tarsal plates of the upper and lower eyelids and can be seen through the palpebral conjunctiva. The tarsal plates are hard and contain approximately 30 glands in the upper eyelid and approximately 20 in the lower eyelid. These glands orient perpendicularly to the eyelid margin and open at the eyelid margin, with the distal end being blind. The meibomian glands secrete large amounts of lipids, which are discharged through the meibomian gland openings at the eyelid margin during blinking and evenly spread across the ocular surface. These glands form the outermost layer of the three-layer tear film, reducing tear evaporation and lubricating the ocular surface. Reduced meibomian gland secretion and discharge accelerates tear evaporation, leading to dry eye. MGD is categorized as either insufficient secretion or impaired discharge, with the latter being the most common type. Chronic impaired discharge of meibomian gland lipids leads to the accumulation of obsolete lipids, severely impairing the gland's secretory function. It also causes excessive pressure in the glandular cavity, leading to gland atrophy and further exacerbating the secretory dysfunction. Therefore, unblocking the meibomian glands and dissolving and expelling obsolete lipids within them are currently important and primary clinical treatments for MGD.

[0004] Currently, the meibomian glands can be unblocked by massaging and squeezing the eyelids, which indirectly puts pressure on the meibomian glands and squeezes out the old lipids in the meibomian gland cavity. However, due to the hard texture of the meibomian plates, a large amount of squeezing force is often required to squeeze out the lipids in the meibomian glands, and the patient feels very painful. In addition, the lipids in the meibomian glands need to become liquid before they can be discharged smoothly. MGD causes a large amount of lipids in the meibomian gland cavity to harden and cannot be discharged. Currently, heating is generally used to liquefy the lipids. Studies have shown that when the temperature is 42 degrees, the lipids in the meibomian glands can be dissolved without causing damage to the surrounding tissues. Therefore, the main treatment theory is to combine external heating of the meibomian glands to promote the melting of the old lipids in the meibomian gland cavity and then combine external squeezing to discharge them.

[0005] Currently, the devices that use this principle and are on the market or under development include heat or liquid pulsating dry eye treatment devices, warm pulse dry eye treatment devices, etc. This type of device is similar to manual massage and squeezing in terms of squeezing the meibomian glands. The heating method requires heating the conjunctiva to indirectly transfer heat to the meibomian glands. This process is bound to cause heat loss. At the same time, due to the three-dimensional structure of the meibomian glands and their different depths, the meibomian glands may be heated unevenly, thereby affecting the dissolution and liquefaction of lipids in the meibomian gland cavity. Summary of the Invention

[0006] The purpose of the present invention is to provide a meibomian gland thermal interventional treatment device to solve the problem that some lipids cannot be completely liquefied after heating the meibomian gland cavity, improve the discharge efficiency of lipids in the gland cavity, and thus enhance the treatment effect of meibomian gland blockage.

[0016] Furthermore, the operating bed is provided with several fixed blocks, the movable frame is provided with several second wedge blocks slidably connected to the fixed blocks, third inclined surfaces are respectively provided on both sides of the second wedge blocks, and a clamping block is slidably connected to the fixed block, and the ends of the clamping block are symmetrically provided with third protrusions that contact the third inclined surfaces.

[0017] Furthermore, a T-slot is provided at the end of the clamping block, a fourth screw is threadedly connected to the fixed block, and a T-block is provided at the end of the fourth screw that is rotatably connected to the T-slot, and both sides of the T-block are respectively in contact with the T-slot.

[0018] Furthermore, a slit lamp is provided on the movable frame, and an elastic bracket is provided between the slit lamp and the movable frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. After the patient lies flat on the operating table, the eyelid hook is placed in the patient's eye socket through the coordination of the movable frame, slider, support rod, and operating table. Then, the support rod is slid on both sides of the slider to drive the eyelid hook to move to both sides, pulling the upper eyelid upward and the lower eyelid downward respectively, thereby opening the patient's eyelids and making it easier for medical staff to observe the location of the patient's meibomian glands, thereby improving the treatment effect of meibomian gland blockage. At the same time, it prevents the patient from blinking during the treatment process, which affects the treatment effect, and eliminates the need for medical staff to continuously hold the patient's eyelids open, thereby improving the treatment efficiency of meibomian gland blockage.

[0021] 2. Power on the heating wire to heat the needle at the end of the injection device to 42 degrees. Then move the injection device so that the needle passes through the meibomian gland opening and is inserted into the bottom of the meibomian gland cavity along the direction of the meibomian gland. After heating the meibomian gland with the needle for 30 seconds, the lipid in the meibomian gland is completely melted. Then, press the block extending to the outside of the tube body to push the piston to slide on the tube body, squeezing the solution in the tube body into the meibomian gland, thereby flushing the meibomian gland cavity, accelerating the discharge of lipids in the meibomian gland, and thereby improving the discharge efficiency of lipids in the gland cavity and enhancing the treatment effect of meibomian gland blockage.

[0022] 3. When the lateral position of the eyelid hook needs to be adjusted on the operating table, the restriction on the sliding of the slider on the movable frame is released by the cooperation between the limit block, the first protrusion, the first wedge block, and the groove. Then, the limit block is restricted from sliding on the slider by the cooperation between the slider, the second screw, and the guide block, which facilitates the subsequent adjustment of the position of the slider on the movable frame, improves the efficiency of the eyelid hook position adjustment, and thus improves the efficiency of the treatment of meibomian gland obstruction;

[0023] By sliding the slider on the movable frame so that the eyelid hook and the eyeball are on the same horizontal line, the slider, the first screw, the second screw, the guide block, the movable frame, the first spring, the limit block, the first protrusion, the groove, the conical surface, the first inclined surface, and the second inclined surface are cooperated to limit the sliding of the slider relative to the movable frame, thereby preventing the external force from accidentally driving the slider to slide on the movable frame during surgery, thereby affecting the fixation effect of the eyelid hook on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage; in addition, according to actual needs, the slider can be fixed at different positions to avoid the slider from moving slightly on the movable frame during the fixation process, thereby affecting the effect of the eyelid traction mechanism on fixing the patient's eyelid, thereby further improving the treatment effect of meibomian gland blockage;

[0024] 4. When the longitudinal position of the eyelid hook needs to be adjusted on the operating table, the cooperation among the slider, support rod, ball bearing, groove, and second spring facilitates the adjustment of the position of the support rod on the slider, thereby improving the efficiency of eyelid hook position adjustment and thus improving the efficiency of treatment for meibomian gland obstruction;

[0025] When the eyelid hook is above the eyeball, the slider, the third screw, and the ball bearing cooperate to limit the support rod from sliding on the slider. This prevents the slider from accidentally sliding on the movable frame due to external forces during surgery, which would affect the eyelid hook's ability to secure the patient's eyelid, thereby improving the treatment effect on meibomian gland obstruction.

[0026] 5. After the two corresponding eyelid hooks are respectively hung on the patient's upper eyelid and lower eyelid, the support rod is slid on the slider to make the eyelid hook slide relative to the support rod and compress the third spring provided between the support rod and the eyelid hook. The rebound force generated by the compression of the third spring applies a pulling force to the upper eyelid and the lower eyelid, making them in an open state, making it easier for medical staff to observe the location of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process affecting the treatment effect, and there is no need for medical staff to continuously hold the patient's eyelids open, thereby improving the treatment efficiency of meibomian gland blockage;

[0027] 6. When the vertical position of the eyelid hook needs to be adjusted on the operating table, the movable frame, the second wedge block, and the fixed block cooperate to limit the direction of movement of the movable frame, ensuring that the movable frame moves vertically, avoiding the need to readjust the horizontal and vertical positions of the eyelid hook on the operating table, thereby improving the treatment efficiency of meibomian gland obstruction;

[0028] When the two corresponding eyelid hooks are in contact with the upper eyelid and the lower eyelid respectively, the second wedge block is restricted from moving relative to the fixed block through the cooperation among the fixed block, the fourth screw, the T-shaped block, the T-slot, the clamping block, the third protrusion, the second wedge block and the third inclined surface, thereby achieving the fixation of the movable frame on the operating table, avoiding the external force from accidentally driving the movable frame to slide on the operating table, affecting the fixation effect of the eyelid hooks on the patient's eyelids, and thus improving the treatment effect of meibomian gland blockage; at the same time, it is avoided that the fourth screw drives the clamping block to rotate, affecting the fixation of the movable frame on the operating table, and thus improving the treatment effect of meibomian gland blockage.

Then, the support rod 4 is slid on the slider 3 so that the two eyelid hooks 5 are respectively above the patient's upper eyelid and lower eyelid. Then, the movable frame 2 is slowly lowered to a certain height on the operating bed 1 to hook the eyelid. The hook 5 is placed in the patient's eye socket, and then the support rod 4 is slid on the slider 3 to both sides, driving the eyelid hook 5 to move to both sides, pulling the upper eyelid upward and the lower eyelid downward respectively, so that the patient's eyelids are opened, making it easier for medical staff to observe the location of the patient's meibomian glands, thereby improving the treatment effect of meibomian gland blockage; at the same time, it prevents the patient from blinking during the treatment process, affecting the treatment effect, and does not require the medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage; the eyelid hook 5 can be made of silicone to avoid rigid contact between the eyelid hook 5 and the eyelid during the process of opening the eyelid, resulting in damage to the eyelid, thereby improving the treatment effect of meibomian gland blockage;

[0044] The hot shock intervention mechanism includes a tube body 6 and a piston 7 slidably arranged on the tube body 6, the end of the piston 7 is provided with a pressing block 8 extending to the outside of the tube body 6, the end of the tube body 6 is provided with a needle 9, and also includes a heating wire 10 sleeved on the outside of the tube body 6 and connected to the needle 9; the heating wire 10 is energized to heat the needle 9 at the end of the injection device to 42 degrees, and then the injection device is moved so that the needle 9 passes through the meibomian gland opening and is inserted into the bottom of the meibomian gland cavity along the direction of the meibomian gland. After the meibomian gland is heated by the needle 9 for 30 seconds, the lipid in the meibomian gland is completely melted; then the pressing block 8 extending to the outside of the tube body 6 is pressed to push the piston 7 to slide on the tube body 6, squeezing the medicine in the tube body 6 into the meibomian gland, thereby flushing the meibomian gland cavity, accelerating the discharge of lipids in the meibomian gland, and thereby improving the discharge efficiency of lipids in the gland cavity, and improving the treatment effect of meibomian gland blockage.

[0045] Preferably, Figure 2 and Figure 3 As shown, a card plate 11 is provided on both sides of the movable frame 2, and a plurality of grooves 12 are provided on the card plate 11. A limit block 13 is slidably connected to the slider 3. The end of the limit block 13 is provided with a plurality of first protrusions 14 and a first wedge block 15 is slidably connected. One side of the first protrusion 14 and the first wedge block 15 is respectively provided with a first inclined surface 16 and a second inclined surface 17 in contact with the groove 12. The resistance generated after the first inclined surface 16 and the second inclined surface 17 contact the groove 12 limits the sliding of the slider 3 relative to the movable frame 2, thereby preventing the external force from accidentally driving the slider 3 to slide on the movable frame 2 during the operation, affecting the fixing effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage; in addition, the slider 3 can be fixed at different positions according to actual needs, thereby avoiding the slider 3 from moving slightly on the movable frame 2 during the fixing process, affecting the effect of the eyelid traction mechanism on fixing the patient's eyelid, and further improving the treatment effect of meibomian gland blockage.

[0046] Preferably, Figure 3As shown, a first spring 18 is provided between the limit block 13 and the slider 3 for realizing automatic resetting of the limit block 13 without the need for the medical staff to toggle, thereby avoiding the slider 3 from moving slightly on the movable frame 2 during the toggle process, affecting the effect of the eyelid traction mechanism in fixing the patient's eyelid, and further improving the therapeutic effect of meibomian gland obstruction; the end of the limit block 13 is provided with a guide block 19 slidably connected to the slider 3, which guides the sliding of the limit block 13 on the slider 3; the guide block 19 is threadedly connected to a first screw 20, and the end of the first screw 20 is provided with a conical surface 21 in contact with the first wedge block 15, thereby driving the wedge block to slide on the slider 3, and through the resistance generated by the first inclined surface 16 and the second inclined surface 17 contacting the groove 12, limiting the sliding of the slider 3 relative to the movable frame 2, The second screw 22 is threadedly connected to the slider 3, and the end of the second screw 22 contacts the guide block 19 to limit the sliding of the limit block 13 on the slider 3. When adjusting the position of the slider 3 on the movable frame 2, it is convenient to subsequently adjust the position of the slider 3 on the movable frame 2, thereby improving the efficiency of adjusting the position of the eyelid hook 5 and thus improving the treatment efficiency of meibomian gland blockage. After fixing the position of the slider 3 on the movable frame 2, the external force is prevented from accidentally driving the limit block 13 to move, thereby affecting the fixing effect of the slider 3 on the movable frame 2, thereby ensuring the stability of the overall structure and improving the treatment effect of meibomian gland blockage.

[0047] Preferably, Figure 3 As shown, a slide groove 23 is provided at the end of the limit block 13, and a second protrusion 24 is provided on the first wedge block 15, which is slidably connected to the slide groove 23, to prevent the wedge block from deviating from the track and affecting the fixing effect of the slider 3 on the movable frame 2, thereby ensuring the stability of the overall structure and improving the treatment effect of meibomian gland blockage.

[0048] Preferably, Figure 4 As shown, the support rod 4 is provided with a plurality of grooves 25, and the slider 3 is slidably connected with a ball 26 in contact with the groove 25, and a second spring 27 is provided between the ball 26 and the slider 3. By sliding the support rod 4 on the slider 3, the force generated by the contact between the ball 26 and the groove 25 drives the ball 26 to move outward, and compresses the second spring 27 between the ball 26 and the slider 3 until the ball 26 moves into the next groove 25, and under the action of the rebound force of the second spring 27, the ball 26 is driven to reset and make contact with the next groove 25, so as to facilitate the adjustment of the position of the support rod 4 on the slider 3, improve the efficiency of the position adjustment of the eyelid hook 5, and thereby improve the treatment efficiency of meibomian gland blockage.

[0049] Preferably, Figure 4 As shown, a third screw 28 is threadedly connected to the slider 3, and the second spring 27 is sleeved on the outside of the third screw 28. The end of the third screw 28 is in contact with the ball 26. When the eyelid hook 5 is above the eyeball, the third screw 28 is tightened on the slider 3 so that its end is in contact with the ball 26. The resistance generated after the contact limits the movement of the ball 26 toward the outside, and the resistance generated after the ball 26 contacts the groove 25 limits the sliding of the support rod 4 on the slider 3, thereby preventing the external force from accidentally driving the slider 3 to slide on the movable frame 2 during the operation, affecting the fixing effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage.

[0050] Preferably, Figure 5 As shown, the eyelid hook 5 is slidably set on the support rod 4, and a third spring 29 is provided between the support rod 4 and the eyelid hook 5.

The rebound force generated by the compression of the third spring 29 applies a pulling force to the upper eyelid and the lower eyelid, so that they are in an open state, which is convenient for medical staff to observe the position of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage.

[0051] Preferably, Figure 6 As shown, the operating bed 1 is provided with a plurality of fixed blocks 30, and the movable frame 2 is provided with a plurality of second wedge blocks 31 slidably connected to the fixed blocks 30, which limit the direction of movement of the movable frame 2 and ensure that the movable frame 2 moves vertically, avoiding the need to readjust the horizontal and vertical positions of the eyelid hook 5 on the operating bed 1, thereby improving the treatment efficiency of meibomian gland obstruction; third inclined surfaces 32 are respectively provided on both sides of the second wedge blocks 31, and the fixed block 30 is slidably connected with a clamping block 33, and the end of the clamping block 33 is symmetrically provided with a third protrusion 34 that contacts the third inclined surface 32. The third protrusion 34 provided on one side of the clamping block 33 contacts the third inclined surface 32 on the second wedge block 31. The friction force generated after the contact limits the movement of the second wedge block 31 relative to the fixed block 30, thereby achieving the fixation of the movable frame 2 on the operating bed 1, avoiding the external force from accidentally driving the movable frame 2 to slide on the operating bed 1, affecting the fixation effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland obstruction.

[0052] Preferably, Figure 6As shown, the end of the clamping block 33 is provided with a T-slot 35, and the fixing block 30 is threadedly connected to a fourth screw 36, and the end of the fourth screw 36 is provided with a T-block 37 rotatably connected to the T-slot 35, and the two sides of the T-block 37 are respectively in contact with the T-slot 35, so that the fourth screw 36 drives the clamping block 33 to move on the fixing block 30, and contacts the third inclined surface 32 on the second wedge block 31 through the third protrusion 34 provided on one side of the clamping block 33, thereby achieving the fixation of the movable frame 2 on the operating bed 1, avoiding the external force from accidentally driving the movable frame 2 to slide on the operating bed 1, affecting the fixation effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage; at the same time, it is avoided that the fourth screw 36 drives the clamping block 33 to rotate, affecting the fixation of the movable frame 2 on the operating bed 1, thereby improving the treatment effect of meibomian gland blockage.

[0053] Preferably, Figure 1 and Figure 2 As shown, a slit lamp 38 is provided on the movable frame 2, and an elastic bracket 39 is provided between the slit lamp 38 and the movable frame 2. By bending and changing the shape of the elastic bracket 39, the illumination angle of the slit lamp 38 is adjusted, which makes it easier for medical staff to observe the location of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage.

[0054] Example 1

[0055] The present invention provides a meibomian gland heat shock interventional treatment device, such as Figure 1 、 Figure 2 and Figure 7 As shown, after the patient lies flat on the operating bed 1, the slider 3 is slid on the movable frame 2 so that the support rod 4 is in the same straight line with the patient's eyeball, and then the support rod 4 is slid on the slider 3 so that the two eyelid hooks 5 are respectively above the patient's upper eyelid and lower eyelid, and then the movable frame 2 is slowly lowered to a certain height on the operating bed 1, and the eyelid hooks 5 are placed in the patient's eye sockets, and then the support rods 4 are slid on the slider 3 to both sides respectively, driving the eyelid hooks 5 to move to both sides, pulling the upper eyelid upward and the lower eyelid downward respectively, so that the patient's eyelids are opened, making it easier for medical staff to observe the position of the patient's meibomian glands, thereby improving the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously hold the patient's eyelids open, thereby improving the treatment efficiency of meibomian gland blockage;

[0056] Then, the heating wire 10 is energized to heat the needle 9 at the end of the injection device to 42 degrees. Then, the injection device is moved so that the needle 9 passes through the meibomian gland opening and is inserted into the bottom of the meibomian gland cavity along the direction of the meibomian gland. After the needle 9 heats the meibomian gland for 30 seconds, the lipid in the meibomian gland is completely melted. Then, the pressing block 8 extending to the outside of the tube body 6 is pressed to push the piston 7 to slide on the tube body 6, squeezing the liquid in the tube body 6 into the meibomian gland, thereby flushing the meibomian gland cavity, accelerating the discharge of lipids in the meibomian gland, and thereby improving the discharge efficiency of lipids in the gland cavity and enhancing the therapeutic effect of meibomian gland blockage.

[0057] Finally, pull out the needle 9, wipe the end with alcohol and let it dry naturally, and repeat the above process to heat and rinse the other meibomian glands internally.

[0058] Example 2

[0059] On the basis of Example 1, Figure 2 and Figure 3 As shown, when it is necessary to adjust the lateral position of the eyelid hook 5 on the operating table 1, the limiting block 13 is pulled outward so that the first protrusion and the first wedge block 15 provided at the end thereof slide out of the groove 12, thereby releasing the restriction on the sliding of the slider 3 on the movable frame 2. Then, the second screw 22 is tightened on the slider 3 so that it contacts the guide block 19. The resistance generated limits the sliding of the limiting block 13 on the slider 3, facilitating the subsequent adjustment of the position of the slider 3 on the movable frame 2, improving the efficiency of the position adjustment of the eyelid hook 5, and thereby improving the efficiency of the treatment of meibomian gland obstruction.

[0060] After the eyelid hook 5 and the eyeball are on the same horizontal line by sliding the slider 3 on the movable frame 2, the second screw 22 is loosened on the slider 3 to release the restriction of the guide block 19 on the movable frame 2, and under the action of the rebound force generated by the compression of the first spring 18, the limit block 13 is driven to move inward until the first inclined surface 16 provided on the first protrusion 14 on the limit block 13 contacts the groove 12, and then the second screw 22 is tightened on the slider 3 to limit the limit block 13 from sliding on the slider 3, and then the first screw 20 is tightened on the guide block 19, and the tapered surface 21 provided at the end of the first screw 20 contacts the first wedge block 15, and the component force generated will drive the wedge The block slides on the limit block 13 until the second inclined surface 17 provided on one side of the wedge-shaped block contacts the groove 12, and the resistance generated by the contact between the first inclined surface 16 and the second inclined surface 17 and the groove 12 limits the sliding of the slider 3 relative to the movable frame 2, thereby preventing the external force from accidentally driving the slider 3 to slide on the movable frame 2 during the operation, affecting the fixation effect of the eyelid hook 5 on the patient's eyelid, and thus improving the treatment effect of meibomian gland blockage; in addition, according to actual needs, the slider 3 can be fixed at different positions to avoid the slider 3 from moving slightly on the movable frame 2 during the fixation process, affecting the effect of the eyelid traction mechanism on fixing the patient's eyelid, and further improving the treatment effect of meibomian gland blockage.

[0061] Example 3

[0062] On the basis of Example 1, Figure 4 and Figure 5 As shown, when the longitudinal position of the eyelid hook 5 needs to be adjusted on the operating table 1, the support rod 4 is slid on the slider 3. The force generated by the contact between the ball 26 and the groove 25 drives the ball 26 to move outward, and compresses the second spring 27 between the ball 26 and the slider 3 until the ball 26 moves into the next groove 25. Under the action of the rebound force of the second spring 27, the ball 26 is driven to return to its original position and contact the next groove 25, thereby facilitating the adjustment of the position of the support rod 4 on the slider 3, improving the efficiency of the position adjustment of the eyelid hook 5, and further improving the efficiency of the treatment of meibomian gland obstruction.

[0063] When the eyelid hook 5 is above the eyeball, the third screw 28 is tightened on the slider 3 so that its end contacts the ball 26. The resistance generated by the contact restricts the ball 26 from moving outward. The resistance generated by the contact between the ball 26 and the groove 25 restricts the support rod 4 from sliding on the slider 3. This prevents the slider 3 from being accidentally driven to slide on the movable frame 2 by external forces during the operation, thereby affecting the fixation effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage.

[0064] In addition, after the two corresponding eyelid hooks 5 are respectively hung on the patient's upper eyelid and lower eyelid, the eyelid hook 5 slides relative to the support rod 4 by sliding the support rod 4 on the slider 3, and compresses the third spring 29 provided between the support rod 4 and the eyelid hook 5. The rebound force generated by the compression of the third spring 29 applies a pulling force to the upper eyelid and the lower eyelid, so that they are in an open state, which is convenient for medical staff to observe the location of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage.

[0065] Example 4

[0066] On the basis of Example 1, Figure 6 As shown, when the vertical position of the eyelid hook 5 needs to be adjusted on the operating table 1, the movable frame 2 is moved up and down, and the second wedge block 31 provided on the movable frame 2 slides on the fixed block 30 to limit the movement direction of the movable frame 2, ensuring that the movable frame 2 moves vertically, avoiding the need to readjust the horizontal and vertical positions of the eyelid hook 5 on the operating table 1, thereby improving the treatment efficiency of meibomian gland obstruction;

[0067] When the two corresponding eyelid hooks 5 are in contact with the upper eyelid and the lower eyelid respectively, the fourth screw 36 is tightened on the fixing block 30, and the two sides of the T-shaped block are in contact with the T-slot 35 respectively, and the T-shaped block 37 is rotatably connected to the T-slot 35, so that the fourth screw 36 drives the clamping block 33 to move on the fixing block 30, and contacts the third inclined surface 32 on the second wedge block 31 through the third protrusion 34 provided on one side of the clamping block 33. The friction force generated after the contact limits the movement of the second wedge block 31 relative to the fixing block 30, thereby achieving the fixation of the movable frame 2 on the operating bed 1, avoiding the external force from accidentally driving the movable frame 2 to slide on the operating bed 1, affecting the fixation effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland obstruction; at the same time, it is avoided that the fourth screw 36 drives the clamping block 33 to rotate, affecting the fixation of the movable frame 2 on the operating bed 1, thereby improving the treatment effect of meibomian gland obstruction.
